| The development of innovative chrome-free basic bricks based on electrofused MgO-CaZrO3 technology using as ceramic bonding two different types of spinel (hercynite and magnesium-aluminium spinel) to improve their properties is presented. Microstructural, physical, mechanical, and thermal properties of electrofused MgO-CaZrO3 matrix were determined. Static and dynamic resistance tests by chemical attack of cement raw constituents were carried out. The results showed that thermo-mechanical properties of new bricks significantly improved with increasing spinel content. Microstructural analysis revealed that the spinel phase aided to develop a strong bond between the magnesia and calcium zirconate refractory phases. Finally, this refractory matrix exhibits a good thermal stability and excellent chemical resistance against cement raw meal. | |
